There is an asymmetry in the OpenType specification: Some variation
fonts come with a named default instance, some not.  I decided to
completely separate named instances from `normal' fonts, at the cost
of adding the unnamed default instance to the list of instances.

In other words, the list of instances in FreeType is *always*
complete.  This means that for variation fonts you never have to look
at the non-instanced face.
